Use the sr20det transmission,I think the ka transmission fits but 5th gear is a little taller.If you have the sr20det transmission use that one.

So you're saying that the KA transmission will work with a redtop motor?

KA transmission is no taller or shorter from a turbo SR20 transmission. All gears will be the same ratio. As for mounting the transmission itself, you will have to remove the KA transmission bellhousing and replace it with the SR bell housing (front half of transmission). The rear half is just about identical to the SR transmission.

WHere can I get the SR bellhousing by itself? I cant find em in eBay either.

5th Gear ratio is different.
